I started using a site to help keep me focused while I do remote work. It uses the pomodoro method of 25 minutes of intense work, but with a buddy. Social Pomodoro, http://socialpomodoro.com, and it’s free and no signup.
It’s been helpful for my productivity, and keeps my ADD at bay. I definitely get more than 25 minutes worth of work done during the 25 minute session. Give it a try if you could use a remote study/accountability buddy.
